A method of electrolyzing brine in a cell using a mercury cathode comprises mixing part of the dilute salt solution obtained at the outflow end of the cell with saturated alkaline solution from which impurities have been removed, and recirculating said mixture to the inlet end of the ...
The electrolysis of aqueous salt solutions in permselective membrane electrolytic cells is well documented in the literature as are the advantages and disadvantages associated therewith. It is known, for example, that when employing such cells for the production of sodium hydroxide (caustic soda) and ...

PURPOSE:In ion exchange membrane electrolysis of aqueous alkaline metal salt solution, gas phase pressure in cathode chamber is maintained at a specified level higher than atomospheric pressure, thereby to reduce voltage between electrodes. CONSTITUTION:In ion exchange membrane electrolysis of KC1 or NaC...
278, cathodes were coated by plasma spraying or flame spraying an admixture of particulate cobalt and particulate zirconia. When these electrodes are used for the electrolysis of water or an aqueous alkali metal halide salt solution, they are said to give prolonged lowering of hydrogen overvoltage....
Carbon dioxide fixation involves producing sodium hydroxide through electrolysis (10) of a saturated saline solution, in which sodium chloride reacts with water to give sodium hydroxide, chlorine and hydrogen gases. The recovered sodium hydroxide is added to sea water, so that magnesium chloride and...
The study presents the economic efficiency of direct electrolysis of natural waters in comparison with the waters artificially prepared by electrolysis of the 3% sodium salt solution. The study used sea water (Black sea water); mineral w... LN Fesenko,IV Pchelnikov,RV Fedotov - International Co...
The method includes the steps of placing the cans in an electrolyte medium, preferably a salt water solution, and positioning a carbon depolarizer in the electrolyte to form an aluminum-air cell. A cup-shaped, inverted, carbon depolarizer and suitable mounting structure for positioning the ...
Electrolysis of a concentrated aqueous solution of NaCl between two Pt electrodes gives at cathode and anode, respectively. View Solution Assertion(A):When an aqueous solution ofKNO3is electrolyzed, potassium is liberated at the cathode. Reason(R):K+ions are discharged at cathode andNO−3at ano...
Fused Salt Electrolysis and ElectrothermicsIt is well known that noble metals such as copper can be electrodeposited at high current density from aqueous solution. However, hydrogen evolution may take place as a competitive reaction when cathodic deposition of less-noble metals such as Fe and Ni ...
